摘　　要：目的探讨MRI测量胫骨平台后倾角、股骨髁间窝宽度以及髁间窝宽度指数(NWI)与前交叉韧带(ACL)损伤的相关性。方法选取2017年1月至2019年1月于本院就诊并经MRI明确的89例ACL损伤患者作为研究对象。根据MRI以及关节镜检查结果将患者分为关节稳定组(仅MRI下前交叉韧带呈长T1、长T2信号)47例与关节重建组(MRI下前交叉韧带呈长T1、长T2信号且前交叉韧带完全断裂)42例,另选取接受膝关节MRI检查的健康人员50例作为对照组,比较各组患者胫骨平台后倾角、股骨髁间窝宽度以及NWI参数与前交叉韧带损伤的相关性。结果关节稳定组与关节重建组患者髁间窝宽度、NWI、内外侧胫骨平台后倾角比较差异无统计学意义;但关节稳定组与关节重建组患者髁间窝宽度、NWI水平均明显低于对照组,胫骨平台后倾角明显高于对照组(P<0.05)。结论MRI检查能够准确评估膝关节损伤患者髁间窝宽度、NWI以及胫骨平台后倾角等解剖学参数,而相关性分析认为较低的髁间窝宽度、NWI以及高胫骨平台后倾角是前交叉韧带损伤的重要风险因素。Objective To investigate the correlation between the posterior tilt angle of the tibial plateau, the width of the femoral condyle, and the intercondylar notch width index (NWI) and the anterior cruciate ligament (ACL) injury. Methods A total of 89 patients with ACL injuries who were admitted to our hospital from January 2017 to January 2019 and confirmed by MRI were enrolled. According to the results of MRI and arthroscopy, the patients were divided into the joint stability group (only the MRI under the anterior cruciate ligament with long T1 and long T2 signals) and the joint reconstruction group (MRI under the anterior cruciate ligament with long T1 and long T2 signals and before Forty-two patients with complete rupture of the cruciate ligament were enrolled, and 50 healthy subjects who underwent MRI of the knee joint were selected as the control group. The posterior tilt angle of the tibial plateau, the width of the femoral condyle, and the correlation between NWI parameters and anterior cruciate ligament injury were compared. Results There was no significant difference in the intertrochanteric socket width, NWI, and medial and lateral tibial plateau posterior tilt angle between the joint stability group and the joint reconstruction group, but it was not statistically significant. The width of the litter and the NWI level were significantly lower than those of the control group, and the posterior tilt angle of the tibial plateau was significantly higher than that of the control group (P<0.05). Conclusion MRI can accurately assess anatomical parameters such as intercondylar notch width, NWI, and tibial plateau posterior tilt angle in patients with knee joint injury. Correlation analysis suggests that lower intercondylar notch width, NWI, and high tibial plateau reclining angle are anterior crosses. An important risk factor for ligament injury.
